Spontaneous intracranial hypotension (SIH) results from low cerebrospinal fluid (CSF) volume, typically secondary to a spinal CSF leak. CSF hypovolemia leads to brain sagging, particularly in orthostatic position, and expansion of the intracranial venous compartment. These pathophysiological mechanisms are responsible for the clinical presentation that usually consists of postural headache variably associated with other neurological symptoms. The wide range of clinical manifestations, including the absence of typical headache, may delay diagnosis. Magnetic resonance imaging (MRI) supports diagnosis showing typical findings including subdural fluid collections, pachymeningeal enhancement and brain sagging.

Abstract

Spontaneous intracranial hypotension (SIH) results from low cerebrospinal fluid (CSF) volume, typically secondary to a spinal CSF leak. CSF hypovolemia leads to brain sagging, particularly in orthostatic position, and expansion of the intracranial venous compartment. These pathophysiological mechanisms are responsible for the clinical presentation that usually consists of postural headache variably associated with other neurological symptoms. The wide range of clinical manifestations, including the absence of typical headache, may delay diagnosis. Magnetic resonance imaging (MRI) supports diagnosis showing typical findings including subdural fluid collections, pachymeningeal enhancement and brain sagging.
